KNIFE.

Application filed May 27, 1925, Serial No. 33,226. Renewed March 29,1927.

This invention relates to improvements in knives, and has for itsprimary object the provision of a sharpening means for the blade orblades thereof, such sharpening means being in the nature of a Whetstoneor the like which forms a portion of the handle of the knife and isreadily removable for the application of the blade when it is desired tosharpen the latter.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawings, 5and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of a pocket knife constructed in accordancewith the present invention,

Fig. 2 is a similar view with parts removed,

Fig. 3 is a sectional view taken on line 33 of Fig. 1, and

Fig. i is a detail view of the sharpenlng 30 stone and its housing.

Referring to the drawings in detail the pocket knife as shown is of theusual construction and the reference numerals 1 and 2 indicate theplates between which is mounted the blade 3. The handle butts 4; and 5are fixed to the plates through the me dium of a pin 6 which also passesthrough a spacing block 7 for the plates 1 and 2 as clearly shown inFig. 3. Extending 1nwardly from the handle butt 4 is a stud 6 adapted tobe received in a recess 7 formed in one end of the housing 8 and thesharpening stone 9. The housing 8 for the stone 9 is formed with anouter wall 10, side walls 11 and 12 and end walls 13 and let. Extendinginwardly from the side walls 11 and 12 and the end wall 13 are tongues15 engaging the sharpening stone for retaining the same operativelyassociated withln the housing. The end wall 14; is provided with aprojection 16 which cooperates with the tongues 15, and a recess 17extends through the end wall 1 1 for receiving the inner end of asliding block 17 having a projection 16' thereon for that purpose. Thesliding block is formed with a slot 18 through which passes a pin 19which also passes through the handle butt 20 and a cover plate 21 whichis arranged above the spring chamber 22, for retaining these parts inposition as shown in Fig. The sliding block is substantially T-shaped inconfiguration and has passing therethrough a pin 23 which is arranged inthe spring chamber and is acted upon by a leaf spring 24; and in orderthat the sliding block can be conveniently operated there is provided inits outer end a finger-nail engaging groove 25.

A handle plate 26 is secured to the plate 2 and arranged between thehandle butts 5 and 20.

From the above description and drawings it will be readily apparent thatthe device which forms the subject-matter of the present invention isextremely simple and forms a portion of the knife handle, such portionbeing readily removable, whereby it may be used for sharpening the blade3 of the knife shown.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended' claims.

hat I claim is:

1. A knife handle of the character described comprising a pair of spacedplates, butts and a handle plate fixed to one of said spaced plates, ahousing including outer side and end walls removably associated with theother of said spaced plates, a sharp ening stone'received in saidhousing, and

tongues formed on the side and end walls of said housing for retainingsaid stone in the housing.

2. A knife handle of the character described comprising a pair of spacedplates, a handle butt fixed to one of said spaced plates, a studextending inwardly from the handle butt, a sliding block mounted formovement adjacent the opposite end of said spaced plate, a sharpeningdevice removably associated with said plate through the medium of thestud and sliding block, and means including butts secured to theopposite ends of said spaced plates to complete the handle structure.

3. A knife handle of the character described comprising a pair of spacedplates, means associated with one of said spaced plates to form oneportion of said'handle, a butt secured to one end oftheiother of saidspaced plates, a stud projecting from said butt, a substantiallyT-shaped sliding block mounted for movement adjacent the opposite end ofthe'last-mentioned spaced plate, a sharpening element provided with endrecesses for receiving the stud and the adjacentend of the sliding blockrespectively, and a cover plate overlying the sliding block.
